Mo's ordered life is turned upside down when he and his mum move in with his new stepdad and stepsisters, Lottie and Sadie. The home he left behind is just across the street, and there's something not quite right about the new occupant. Other strange new people keep popping into his life, too: a bonkers lollipop man, and a boy called Jax. Who are the weird new people in their town? Do they have any involvement in the disappearance of Mo's dad many years ago? Lottie is determined to find out exactly what's going on, even if it makes Mo mad, and even if it leads them both into serious danger...
